In total eight tests are to be carried out: .. csv-table:: "**Test**", "**Configuration**", "**Type**", "**Description**", "**Master version**" "1", "Core", "900"," MAC3_Core900 .json", "stable" "2", "Core", "1300"," MAC3_Core1300 .json", "stable" "3", "Core", "N4"," MAC3_CoreN4 .json", "stable" "4", "Core", "MONO "," MAC3_MONO .json", "stable" "5", "Core", "TEST "," MAC3_TEST .json", "stable" "6", "Row", "900"," MAC3_Row900 .json", "stable" "7", "Row", "1300"," MAC3_Row1300 .json", "stable" "8", "Row", "N4"," MAC3_RowN4 .json", "stable" For each of these tests, save the mesh in different MED files, then import them into the SMESH module and check that the number of meshes corresponds in the following table: .. csv-table:: "**Test**", "**Configuration**", "**Type**", "**Number of meshes**" "1", "Heart", "900", "32896" "2", "Heart", "1300", "49708" "3", "Heart", "N4", "52820" "4", "Heart", "MONO ", "276" "5", "Heart", "TEST ", "1340" "6", "Row", "900", "3248" "7", "Row", "1300", "4000" "8", "Row", "N4", "4000"
